greater sciatic notch, where it ends, it becomes less distinct, and is often altogether 

 lost. Behind this line is a narrow semilunar surface, the upper part of which 

 is rough and gives origin to a portion of the Glutseus maximus ; the lower part is 

 smooth and has no muscular fibers attached to it. The anterior gluteal line (middle 

 curved line}, the longest of the three, begins at the crest, about 4 cm. behind its 

 anterior extremity, and, taking a curved direction downward and backward, ends

at the upper part of the greater sciatic notch. The space between the anterior 

 and posterior gluteal lines and the crest is concave, and gives origin to the Glutseus 

 medius. Near the middle of this line a nutrient foramen is often seen. The 

 inferior gluteal line (inferior curved line}, the least distinct of the three, begins in 

 front at the notch on the anterior border, and, curving backward and downward, 

 ends near the middle of the greater sciatic notch. The surface of bone included
